Do you think that these vendor agnostic implementations can cahnge with the small cell forum API?
no.

This is the Layer 1 API between the PHY and the MAC/RLC layer. This is _very_ far from the Iuh interface. Compare it with the L1SAP interface of OsmoBTS. And Iuh is on th level of the A interface, not even Abis.
Also, this API is for LTE, not for UMTS.
Do we know any femtos on the market that actually is compatible with this API? And if we have one, can that help us?
You can find transceiver hardware + PHY implementations that offer this L1 API. However, that is not a complete (femto/small) cell, but the hardware plus the PHY.
I don't think anyone will quickly come about and implement all the missing layers, so in the context of developing a NITB with Iuh interface, it doesn't really help.
Or maybe you have some specific models in mind you always wanted to try but never had the time? If you have any recommendations I would be happy to look into them.
I haven't really looked at any femtocells for a very long time.
