Exhibit 31.2
                                                     ------------

I, Patrick G. Mackey, certify that:

1.   I have reviewed this Quarterly Report on Form 10-Q (this
     "Quarterly Report") of Novo Networks, Inc. ("Novo
     Networks").

2.   Based on my knowledge, this Quarterly Report does not
     contain any untrue statement of a material fact or omit to
     state a material fact necessary to make the statements made,
     in light of the circumstances under which such statements
     were made, not misleading with respect to the period covered
     by this Quarterly Report.

3.   Based on my knowledge, the financial statements, and other
     financial information included in this Quarterly Report,
     fairly present in all material respects the financial
     condition, results of operations and cash flows of Novo
     Networks as of, and for, the periods presented in this
     Quarterly Report.

4.   The other certifying officer and I are responsible for
     establishing and maintaining disclosure controls and
     procedures (as defined in Exchange Act Rules 13a-15(e) and
     15d-15(e)) for Novo Networks and have:

     a)   designed such disclosure controls and procedures, or
          caused such disclosure controls and procedures to be
          designed under our supervision, to ensure that material
          information relating to Novo Networks, including its
          consolidated subsidiaries, is made known to us by
          others within those entities, particularly during the
          period in which this Quarterly Report is being
          prepared;

     b)   evaluated the effectiveness of Novo Networks'
          disclosure controls and procedures and presented in
          this Quarterly Report our conclusions about the
          effectiveness of the disclosure controls and
          procedures, as of the end of the period covered by this
          Quarterly Report, based on such evaluation; and

     c)   disclosed in this Quarterly Report any changes in Novo
          Networks' internal controls over financial reporting
          that occurred during Novo Networks' most recent fiscal
          quarter that has materially affected, or is reasonably
          likely to materially affect, Novo Networks' internal
          control over financial reporting.

5.   The other certifying officer and I have disclosed, based on
     the most recent evaluation of internal controls over
     financial reporting, to Novo Networks' auditor and the audit
     committee of Novo Networks' board of directors (or persons
     performing the equivalent functions):

     a)   all significant deficiencies and material weaknesses in
          the design or operation of internal controls over
          financial reporting that are reasonably likely to
          adversely affect Novo Networks' ability to record,
          process, summarize and report financial information;
          and

     b)   any fraud, whether or not material, that involves
          management or other employees who have a significant
          role in Novo Networks' internal controls over financial
          reporting.
