I blogged about data offload earlier, for Femtocells. This traffic offload can be done via a feature called Local IP Access (LIPA). If you have LIPA support in your Home NodeB (HNB) or Home eNodeB (HeNB) then once you have camped on your Femtocell then you can access your local network as well as the network's IP network.This would mean that you can directly print from your mobile to the local printer or access other PC's on your LAN. Note that I am also referring to access via Dongle as Mobile access though in practice I dont see much point of people just using dongles when they are in their Home Zone. Every laptop/notebook/netbook is now Wifi enabled so this situation doesnt benefit much for the dongle access.
I am sure there are quite a few unresolved issues with regards to the Security of the data, the IP address allocation, QoS, etc.
Continuous computing have a white paper on LIPA available that can be obtained by registering here. Anyway, enough information is available even without getting the PDF.There is also a small presentation here that gives a bit of idea on LIPA.
As usual any comments, insights and references welcome.

I wonder how handover between HeNB and a provider's eNB is handled, do they connect on an X2 interface? So I could access an eNB from my home network?
Or is handover prohibited with femtocells?
