For example, if you end up running the Helix distribution of Gnome with Nautilus installed on a Red Hat system, you'll have 3 update networks to interface with. You have the Red Hat update agent with RHN, Nautilus which interfaces with the Eazel Services for updating and installing software, and Helix Code's update agent. All three of these companies seem to be targeting software upgrades for Linux. Granted there are some differences in the way they go about it, but not enough to avoid confusion. You have another option though.
Evolution is in anoncvs.
As is gtkhtml, bonobo, gnome-print and all other projects HelixCode is working on. RedCarpet's development is beginning to look more like Cathedral Building than Bazaar. I must've seen a jillion bazillion Miguel interviews by now. For crying out loud. I've even been flamed by him before.
