Yeah.
For interactive services, where an app responds to an MO SM with an MT SM within a timeframe of at most a few minutes, you can do most NP work very simply under certain conditions, namely when all bearerbox connections go to the operators directly, and not over a service aggregator.
In this case, the MO will only come from the operator who "owns" the handset, i.e. owns the GSM network in which the handset is present. If that handset gets ported, the MO will come from the new network's SMSC.
By remembering the smsc-id from whence an MO came, you will almost never go wrong sending it back to the same smsc-id for the MT replies. No nasty HLR lookups!
It's no good for strongly asynchronous MT-centric services (subscriptions, e-mail notifications, etc) but it will work like a charm for most other cases.

P.S. Sorry Nisan! I pressed "send" there before remembering the dev-list's handling of replies. Not enough coffee...
