Dependant VISA processing time!

People,
I desparately need your help! Me and my wife moved to the UK in 2004. I was then a student and my wife a student dependant. Last May I started work here in the UK on a work-permit VISA obtained from India. However, my wife is still here on her student-dependant VISA which expires on 31-Jan-08!

The issue is: In order to plan her trip back to India to apply for a Work-permit dependant VISA, it would be better if we know what is the processing time for such a VISA.

I know it took 14 working days for my work-permit VISA which was submitted at the Bangalore VFS office.

In gist:
1. On an avg. what would be the processing time for work-permit dependant application?
2. Can she apply ASAP, ie. in late Oct rather than in Jan 08?

Any input is much appreciated!

Thanks in advance,

-Ameet
