How will the Sun acquisition affect Redpill Linpro and it's products? It's not quite clear yet, but I have a few ideas.
Hopefully, the Unbreakable Linux (OEL) thing will go away. Oracle just got a hold of Solaris. OEL doesn't add any value to the RHEL source and should just go and die somewhere. Don't get me wrong - OEL isn't a huge threat, it's just annoying.
If Oracle doesn't quickly state what it will do with Java - there might be a lot of uncertainty and therefore damage. Microsoft would benefit from this and try to take advantage of the situation.
Openoffice will live on and might even get stronger under Oracle. Openoffice does real damage to Microsoft and Oracle loves damaging Microsoft. Go Oracle!
MySQL is a bit odd. They started out as a very simple database - but lately they have, unsuccessfully, tried to make their database into a really complex product. Oracle will probably make it very clear that MySQL shouldn't compete with Oracle and it should do what it does best - being simple, fast data storage with and SQL interface. Oracle will hopefully push MySQL in the directing the drizzle fork is going.
Solaris will of course live on to slowly die together with the other Unix dialects.
