hi Denis and Peter
thx for sharing

1. about bandwidth, this thing one of my consideration because its still
hard to have good internet bandwidth in good price here in indonesia,
especially for our site office, most of it only have about upto 1 mbps
currently  i monitor tcp traffic between my PDC and BDC of current samba 3
installation it only takes about 10 kbps. each server, i hope not so
different with samba 4

2. i will try RODC on site office latter on after finish trial on DC member
on site office
3. if im using RODC, is user-client on site office can change their
password from their pc on site office ?
