I have another question about this.

Is there a default location? This will make it difficult for users
who use both the command line and seqweb or SeqLab and seqweb to
manage their files. I would assume on most systems "nobody" does
not have write privs to the user's home directories. So, a seqweb
user would not be able to save GCG output files or files retrieved
from a database to thier home directories. The user needs to manage
2 sets of files if they have GCG files in their home directory.
Also, what about accounting for disk space usage?

When we received the first beta version of seqweb, it came with a
web server. Has this changed? We have our own web server and a
couple of different document trees for secure pages public pages and
development. I am not anxious to try to change this and add a new
server. The GCG web interfaces we've developed in house run a set
uid program so the web server runs as the user. I think this is
similar to W2H. Is this possible to do with seqweb?
If seqweb is running as "nobody", and a user chooses to keep files
in their home directories read/write only by owner, they will not
have access to them from seqweb.

Yes, but how do I account CPU usage? GCG even comes with some
logging. Running seqweb this way leaves a logfile file filled with
user "nobody" running GCG programs. This can't be a good solution.
