process records parallel on RS why not use HDFS to distribute the jar?
See for dynamic class
loading of jars.

In the first mail you had mentioned that there are various problems in CP?
What are those problems?  Filters are mainly used to work on the Rows/cells
that are retrieved in every region.  Whereas CPs are used to add some user
extensions to the way Servers works in write path or read path.

Not sure if I understand your problem correctly.
