thinking of moving from dish to fiostv: slingbox work?

I've been a satisfied dish customer for years.
However, dish has become very, very expensive for all the premium stuff i want including the french channels.
fios in ny with a comparable film package and french tv5 will save me over $100 a month.

my major concern is how well slingbox works with fios. I have legacy slingboxes and use the dishanywhere interface (often from Paris).

I thank you in advance for your replies.
