problem with WAN links

hi guys

i have an slow link connection in my WAN about 1MB/s for my branch office whtch has 20 Clients, and i want to use VmWare View for the VDI .

also i dont want to put my servers on that office , ii want to host them in my datacentre

is there possible to put a NAS on that Branch office and connect that NAS to my ESXi Host server in my datacentere ,

if that is possible so i can save the OS images on that NAS .?.?.?

another question is that "IS THERE ANY DEFERENT IN THIS CASE"
