System update via remote play?

[GripnRip]

Does anyone know if you ca run a syste update via remote play?  I've never seen an answer to this question, but i'venever really looked that hard.  I'm out of tow until Friday, but i havemy psp with me and I'd love for my ps3 to be up to date when i get home so i don't have to update before getting on the psn.
