Does BandwidthRate apply to bridges. I can (hopefully) guess that RelayBandwidth doesn't. Does the AccountingMax apply.

I am almost certain that all three options apply to bridges as well. Note that BandwidthRate applies to all TCP data (not the TCP headers or DNS traffic), while RelayBandwidth* applies to the _relayed traffic_ only.

I noticed the following in the manual:

If you have bandwidth cost issues, enabling hibernation is preferable to setting a low bandwidth, since it provides users with a collection of fast servers that are up some of the time, which is more useful than a set of slow servers that are always "available".

Does that advice apply equally to bridges, assuming that the Accounting options do apply. Or would it more advantageous for a bridge to be constantly available, as switching bridges isn't as seamless as switching relays.

That's an interesting question. Bridges are required to provide at least 1 Mbit/s bandwidth, but I can't find anything related to uptime requirements (except for the two hours a day minimum). I'd say that the advice therefore also applies to bridges. The Tor client software can be configured to use multiple bridges.
