Koushik Dutta has posted two great updates on his blog about Mono running on the Android powered G1 phone. The code necessary to build Mono on Android is available at the androidmono page.
The first bit is his work to allow Mono code to call Dalvik code as well as the bridge to allow Dalvik/Java to call into .NET code. This is necessary to allow Mono-based applications to call into the phone API and integrate with the existing stack.
The second bit is a cute show of DLR-based IronPython running on the phone.
This of course means that with the bridge in place, any CLR or DLR-based language can access the functionality exposed in Dalvik.
