For the SIM reader, how about using SAP (SIM Access Profile) ?
Originally it's a bluetooth profile
It's not as powerful as PC/SC, because SIM in mind instead of SmartCard,
but it makes it much simpler and lighter (could be integrated in futur
ROM). The specs are small.
There should then be a SAP server for the card reader, and osmocom would
have a SAP client.
This architecture would provide the possibility the access the SIM card
also from a client on a computer, but also have a SIM server on the
computer for osmocom (using standard PC/SC card reader).
