I have a client who is equipped to SBS 2011 on its main site.
The config of the main site (one active directory domain )  :
1 DC server SBS 2011 + 1 DC 2008R2  Standard   +  x Members Servers 2008R2 .

Today after buying a new company we wants to establish a trust relationship with the second site:
Config second site:
One domain active directory : One 2008 Server R2 Standard DC

On the net there is conflicting informations :
The microsoft license  excluded trust relationship on SBS
but some forum articles  shows that people  create this trust relationship with success

Anyone here have experience on this kind of architecture ?

SBS does not allow domain trusts. It will break, the server will periodically shut down, and undoing the damage can be a right pain. Plus, trying to circumvent Microsoft licensing is illegal, and as you yourself said, that is a restriction Microsoft itself lists.

Only solution I see is to demote the SBS DC and Promote one on the member servers as a DC in Site A

You cant just demote SBS. That is unless you have purchased and licensed exchange, installed on a different server and local moved your mailboxes.

Which is the only logical path here. They sound too big for SBS to be practical. Once the domain has been migrated to a "Standard" domain, trusts are possible and normal rules apply.

I don't know how the sites are going to be connected but I have sites connected using VPN and Microwaves.

Both of the sites are in my LAN with only one GC and several DC, DNS, DHCP... AH!!!! I'm running SBS 2003 moving to 2012 with that customers... everything works wells so far.

You only need good speed between the sites to make it happened...!!! :-)

Good Luck!!!
