A new client has asked us to escrow our production code with someone, i.e. 
give our code to someone to hold in safekeeping, in case a giant 
radioactive lizard falls from space onto our office and eats us all :-(  
What experiences do you have and who can you recommend in the UK.

All answers appreciated,
andy

P.S. BTW, we do keep an offsite copy of all our production code, in case 
you were starting to get concerned.
