Hmm... I'm afraid your are talking about reinventing the wheel that
has never been invented. There are NO established protocols for that
that would guarantee a success. In any case you'll need to tweak the 
system to your specific protein/cells/other conditions. 

And personally I believe elctroporation (if designed thoughtfully) is
the easiest way to accomplish this. Of course, you'll need plenty of 
the protein to be introduced...
