Throughput patches

Hi!

I've been reading the different threads about the problem with
throughput, being this the last one (I think):
http://www.mail-archive.com/[email protected]/msg06847.html

Apparently that fixes the outgoing traffic throughput, but impacts
incoming ACKs.

Is there any new version of the patch which fixes this, or any plans
on fixing it soon?
Seems to me to be something important, since many SMSCs limit their
inbound traffic, and not being able to correctly set the throughput
parameters is a big problem.

Also, that patch is EMI/UCP specific and Stuart Beck ported it to SMPP.
If there are intentions on fixing it on Kannel, will it be coded on
each smsc implementation, or will it be abstracted to some more global
place (don't know if it's possible)

Thanks in advance,

Juan
