Deadline count down in working days

[Rick Moynihan <rick@calicojack.co.uk>]

Hi all,

I realise this functionality is probably in org already, but I can't 
seem to find it mentioned anywhere (though perhaps I'm not looking very 
hard).

Currently when I look at my agenda I see this:

gtd:   In              5 d.:  TODO [#A] A particular work related task

The 5d countdown includes weekends however.  Is it possible to get org 
to exclude weekends from these countdowns, so I know how many working 
days I have?

As I use org for both, personal and work related stuff what might be 
nice is if org could calculate work tasks in working-days and personal 
tasks in week-days for the agenda view e.g:

Thursday  27 March 2008
gtd:   In              2 wd.:  TODO [#A] A particular work related task 
:WORK:
gtd:   In              4 d. :  TODO [#A] Arrange holiday insurance 
:PERSONAL:

Where both tasks would be due on the same day (Monday 31 March 2008). 
Here I've changed the suffix for the work task to wd to indicated 
working-days and left the d suffix to indicate days.

Thanks again!

R.
