You can measure the bandwidth use of the vif interfaces in dom0,
either by parsing /proc/net/devices periodically or by polling SNMP.
As you noted the vif name will change every time a domain is
restarted. In Xen 2.x you can use the vifname config directive to
hardcode vif names per domain. You can also do this in 3.0 if you
use a snapshot of -unstable that has this functionality (apologies,
I do not know exactly when it was (re)added).
Finally you could also use iptables in dom0 and the physdev module
to add rules for traffic going in/out particular vifs, and poll its
counters to measure bandwidth.
