Hi again. Well, I've started working on using chimera as a visualization extension for another program and I've got a couple more questions/comments from things I've run into recently. :

1) I just downloaded the latest release, but it fails when I try to install it as non-root with a destination of /home/stevel/chimera (see end).

2) One problem I keep running into is when I go to your web page, I have no way to tell if the version I have is the most recent, or if you've put a new one up. Perhaps you could put an upload date on the webpage. A build number might also not be a bad idea... just a suggestion :^)

3) If chimera is installed as root, is there some way for users to include their own extensions ?

4) Since I'm trying to use chimera as a sort of integral extension to one program, and may increase this usage in future, I just wanted to insure that it's not suddenly going to be a commercial product (for academic users anyway). Is this something I can rely on ?

5) Finally, a technical question. Currently I'm spawning a new thread to handle the interprocess communication (I'm using unix-domain sockets for security at the moment). Anyway, the thread solution has a number of problems, of course, largely due to bugs at the moment. I was considering trying to implement an event-loop function instead, perhaps by registering an idle-event in Tk. Just wondering if there is anything I should be aware of before tackling this approach...

Thanks, and I really do appreciate all the work you guys have put into chimera. I really hope that the method I'm working on will work. If so, I should be able to garner a couple of hundred additional users for you :^)
