Not really. The problem was that at that moment, the Fuel's design
regarding Streams was not very beatiful and we were depending on a lot of
messages on Streams. Now in Fuel 1.8 we have reified FLEncoder and
FLDecoder and hence we depend only on a few methods for streams:

Write stream:

nextPut: aSmallInteger
nextBytesPutAll: aBytesObject
nextWordsPut: aWordObject

Read stream:

next:numberOfBytes into: aBytesObject
nextInto: aCollection
fuelNextWordsInto: aWordsObject

So if someone help me to figure it out how to do it in XStreams let me know
and I try.  Moreover, we have also improved the tests and now you can run
all of them with the steam you want. Basically, you have to subclass
FLStreamStrategy and implement #writeStreamDo: and #readStreamDo:. So far
we have FLByteArrayStreamStrategy, FLFileStreamStrategy,
FLMultiByteStreamStrategy and FLFileSystemFileStreamStrategy (for FS).

So...the procedure is to create FLXSteamsStrategy accordly and start trying
to create (as extensions) the needed methods ;)
