Well you could always try sending it an ACTION_SEEK (or whatever) packet
and see if it works. Or call Seek() and see if that works.

Depends on the person writing the pipe. Most folks probably wouldn't 
include the ability to seek since there is no meaning associated with
what it means to seek. Others might make up their own policies and go
for it. 

In the IFF case since your "files" are nearly always going to be bigger
than a pipe buffer you will probably want to build the complete file in
memory and _then_ stuff it out through a pipe or what have you. Also it
makes for the ultimate in buffering and hence speed of output.
