No, it (speed) is quite important.  I'd personally like to stream
megabytes of data (in a statistical, "flat-file"-ish sense) and
process it at the same time.

The only rationale for XML-RPC is "simplicity".  We'll keep it in
quotes, since I'm saying that out of context and it implies a set
decision-making criteria behind it.

Again, I'm not interested in baiting, just finding out what has been
explored/considered, and what the framework is. 

We (one of my "affiliations") are looking into wet-lab
informatics/data processing, as well as cross-institution/group
database collection (wet lab + epidemiological/health services data).
Piper has the right requirements, if implemented reasonably quickly,
to be a tool we could use (and hence consider developing for, or even
just developing).

Glue is good, and fast drying stable glue is better :-).

best,
