private GSM network + cheap SIP = cheap mobile!

On: Open Source GSM Network At Dutch Hacker Convention

I'm wondering if I'd set up such a network at home, possibly with a normal GSM modem which would act as my "phone" to the outside carrier... So, for example,
- I'm at Vodafone outside the street,
- I go home -> my phone swithces to MyOwnNetwork
- If I call anyone around the house (neighbours, family, etc), it's free
- If I call a landline -> goes through cheap SIP
- If I call a cellphone -> the system would "roaming" me, but for cheap - it would make vodafone believe it's my phone!

How does this smell?:)
