Yes, as long as you don't use your cell phone in a foreign network. Then 
you'd have to pay normal (overpriced) roaming charges. Also if you call 
another cell phone using SkypeOut the carriers still get their revenue:

Unless it is specifically mentioned, the SkypeOut Global Rate is only 
for calling regular landline telephones. Calls to mobile phones are more 
expensive.

Nevertheless, it's a clever idea.
