[PyQt] Python Commander in PyQt?

[Glenn Linderman]

  An off-group response caused me to realize that my original posting 
wasn't clear on the environment in which I am working, nor my "real" 
problem, but rather one step removed from that.  It is easy to fall into 
the trap of asking for what you think you want, based on one's own 
limited knowledge, ideas, and available solutions.  Here is a bit more 
information:

There are two classes of users of my web site: normal users and queries 
are by far the bulk of the requests, and the site has been optimized for 
their needs, including transforming the data from its original sources 
into a different form.  This is a reversible transformation, and lossless.

Then there are a smaller set of data suppliers.  They provide the data 
in the original form, and then it is transformed for the site.  So to 
make their job easier (and understandable), there is a need to provide 
them with the original view of their data, in that form.  But storing it 
in both forms requires too much space... I can keep enough metadata to 
provide the appearance of their original data files, and it is no 
problem to perform the queries to supply the data from their original 
files when they request it, or to accept new data when they supply it.

So probably any protocol would work on the wire, FTP, SFTP, SCP, WebDAV, 
etc., as long as I get to define to the server implementing that 
protocol what the definition of a file is, in code, preferably Python 
code, but Perl would be OK, if something similar enough preexists.

I went down the path of not finding a server implementation of any of 
the well-known protocols that would allow a definition of fake files at 
the back end.... except HTTP.  And I'm unable to obtain control of the 
server ports to even run a non-standard server software if it does 
exist, so I'm limited to HTTP as a transport protocol, although other 
protocols could perhaps be proxied over HTTP, but then standard clients 
probably can't be used either.  So then I started looking for front ends 
that I could tweak to speak HTTP to a custom CGI script.  That's where I 
started this thread, and why I picked this group to ask in, because I'd 
find it useful and interesting educationally to tweak a PyQt front end, 
instead of one written in some other environment.

I'm open to suggestions for tackling the problem from other directions, 
though.
