[GE dev] Where to start?

OK so first I will begin with ideas listed on
http://wiki.gridengine.info/wiki/index.php/GSoCIdeas .I could not find
the status of these projects ie whether they were allotted to some one
or not in gsoc2007. So assuming few of these still need some work.
The ideas I am interested in :

1.DRMAA Web Services Specification and Binding
What exactly related to DRMAA needs to be done here. Any particular
person I should contact regarding this.

2.RSS/ATOM Feed for job status
To generate RSS feeds can I use python or do I have to stick to
javascript. I guess the XML about the job status will be fetched from
xml-qstat. Then they would have to be embedded in the XMl format of
RSS and shown to user as RSS feeds.

3.A NetBeans plugin for DRMAA and/or OpenM
Can anybody tell me the status of this. I will also put this query up
on NetBeans mailing list

4.Integration with a VMM (such as Xen) to dynamically set up an
execution environment (in the form of a virtual machine) before
running a job
Will this be done using libvirt or is libvirt the solution to this problem.

5.IPv6 support

Plus there are many tasks which deals with running windows based
programs on linux using a VM. Are these tasks specific to a particular
VM or generic in nature.

Regarding my machine having IPMI, I dont think it will have IPMI. Its
a dell laptop. Still I have writen a mail to Dell asking about it.

And I find working for execution deamon and qmaster deamon interesting too.

So the thing is I find most of the ideas you have given interesting.
Now I wish to be associated with SGE for a long period of time,
outside the time scope of this competition. And the thing is I am not
able to measure the amount of time each of these ideas will take to be
implemented.
I choose SGE because of my general interest in Grid computing. And
since you people have more knowledge regarding the code base of SGE it
will be great if you people can suggest me projects i should work
upon( can be more that 1 project too) which can be completed in these
4-5 months including understanding the required code base.

As far as my skills go, I am comfortable in c/c++, python, HTML and
javascript. I haven't learn java till now, but if any of the project
requires quite a lot of work in java i will learn it too.

ps:- The website of the competition i am participating in quotes that
"it should not be bug fixes and should i require substantial amount of
coding or/and research"
Waiting for replies
