It would be great if someone with better knowledge could give some light on this, and if LGPL dependencies can be used.
That would be great, indeed. What I've been able to gather is the same as you: as jclouds, we shouldn't have any problem releasing this.
The point Alex was originally trying to make when he raised this, though (as far as I understood) was a different one: if we suddenly include an LGPL lib, it becomes impossible for anyone to bundle jclouds in a product that is not LGPL-compliant.
Of course, they could jump through some hoops to try to exclude it (like Brooklyn did), but my guess is that, if they know, they would simply skip 1.8.1 and future releases until this is fixed. Data on this point would be welcome, but the absence of more evidence I think we should be conservative and take the one datapoint that we have (from Alex) that this is a Real Problem.
