may be i can help? :)  i'm not sure that i understood you properly,
but my own compression program uses several compression algorithms,
written in C, in parallel - i.e. output from first algorithm is piped
to the second and so on. if this is not enough - all these algorithms
are executed via one function, which receives algorithm name and
input/output routines, so i run in parallel, for example:

compress "words" read_func1 write_func1
and
compress "ppm" read_func2 write_func2
