Notes' already noteworthy remote access capabilities are greatly improved in V4. Notes 3's ability to replicate databases to portable PCs and keep these replicas in sync has made it a favorite of road warriors.
Encryption protects locally stored databases.
This mechanism lets a remote client access its home server by connecting to any V4 Notes server in an organization, and passing through i t and any other V4 servers on the network path to its home server. According to Lotus, Notes 3 can handle approximately 200 users per server and V4 now supports up to 1,000 users per server. Some of this increased scalability is due to performance improvements, such as field level database replication, while some is attributable to improvements in hardware and operating systems, like V4's ability to run on higher-end computers with multiple processors. Notes 4 has also been optimized for newer 32-bit operating systems. Jumping on the Internet bandwagon, Notes 4 comes with its own integrated WorldWide Web browser for your surfing convenience.
