I don't know anything about Oracle buying Sleepycat. However, should this rumor indeed be true, then I don't see any impact on Ice and our licensing, regardless of whether commercial or GPL. Without going into details, we have a solid agreement with Sleepycat software that allows us to incorporate Berkeley DB into Ice, and to sell such combined product to our customers. This agreement would not be invalidated by any company acquiring Sleepycat software.
One long term impact might be that Berkeley DB becomes even more popular than it already is. Berkeley DB is a fantastic database, and with the backing of Oracle, it might become even more attractive for large companies. In any case, this is of course pure speculation. As I wrote above, I don't know anything about any talks between Oracle and Sleepycat, and I doubt they could tell me about it if I asked them But I do know the guys from Sleepycat, and I trust their judgement.
