Wow, this thread has taken off quickly. I guess I like having "Open" in the name which fits in with other open source projects. OpenWeb?
I also like Pueblo (being from the southwest) as it implies a living community which builds and expands in response to the needs of its people.
Oasis is also nice and short and I like the implication of a pleasant escape from the expensive troublesome commercial toolkits
Agora doesnt do anything for me..
here are some ones that come to mind:
WebWorks
DigitalWorld
Networld
OpenWave
anyway.. just a few thoughts to toss into the hat
