why not set up a free account with www.box.net? unlike free accounts with most other file lockers/cloud storage, the files won't be deleted unless you do it (or unless it gets taken down for other reasons). another option would be dropbox, but that requires installing software, and other stuff, so may not be the best all around option. I upload things to many file lockers, but the only sites that won't delete files after some short period is one of these 2 options, atleast what I have used (all free accounts). 

as for Laputa.... iirc the old dub is still around to some degree. I think it's the R2J DVD that has the old Streamline dub on it. There may (?) also be a UK disc with it, but perhaps I am mixing that up with smth else that has a few releases in the UK (like Cagliostro).
