It is a TODO item means: somebody yet has to implement it. There is no existing work on
it so far.
I think there is little effort in the actual transmission of the SMS over a GPRS channel
itself. The bigger question is who will handle it and where. SMS handling so far was/is
inside the NITB, and GPRS handling is inside the SGSN
So the logical choice is to first externalize the SMSC code from the NITB (or now OsmoMSC
on which Neels is working) and then simply talk to that external smsc from both the SGSN
and the MSC.
In terms of effort, I would assume anywhere between one and two weeks full time for
somebody familiar with the code.

Harald.
