different rates could be handled with --rate yes, but the real problem 
is the deviation of clocks. i.e. even if both source and sink are 44.1, 
they wont be perfectly 44.1. Either the sink will be starved of data or 
it will be overwhelmed. There needs to be some kind of active link 
in-between that can intelligently resample the data appropriately to 
ensure that doesn't happen.

As Lennart said, there is code in module-compbine that does this kind of 
resampling so could form the basis for a properly implementation.

But for many applications the hacky method works OK.
