Too late! All done! :-,
But that would be easy to do; I could simply write a daemon class that consumes
tidbits by spooling them for serving later. The drawback to doing this, is
that one *might* need to run two JVM's -- one for the spooler, one for the
client. I need to think about that...

Hmmm... This sounds more like a middle-tier app than a client app; my
original intent was for a client-only solution. But after reading back on the
subthread between you and Dan, I can see the need for it.
Fortunately, my client engine can pass the tidbits to any class that implements
the callback interface. It shouldn't be too difficult to *completely* mirror
your avid.cgi script, if the consumer class caches the tidbits and serves them
later in an identical fashion. Lemme look into this as well...
