Keg To ?

[warb]

I have had question from a mate that I cant answer, he wants to go from a commercial keg to something to store it, and drink over time.

I have done this with cold bottles straight from my beer tap, but he has guiness, whats required? any suggestions?

Are post mix kegs an option?

not realy, he is not a brewer, maybe i should offer a loan? with a soda stream botte, reg and gun?..

if thats the case, just fill her up from one keg to the PM one? .. what do i need to look out for, considering the type of beer?.
