	This is being discussed in conjunction with Lynx development, and the
consensus is that we need some kind of tag associated with forms which will
transmit the file independently from the client's site to the server for
integration into the form's function.  It would be relatively easy to add a
command in clients to import a user-specified file instead of keyboard input
for form entries, but software using memory instead of disk-file caching could
have problems with this (it would be only a matter of time before a novice
user tried to import the entire GenBank database into the form 8-).

	Once this is worked out and implemented, biologists (and others for
equivalent kinds of services) also need some standards for dealing with
conversions of files.  For example, one may need to convert GCG-format
sequences to FastA-format if that's what the form function is expecting.
