My estimation is that Qt3 will be used for applications, especially by ISVs, 
for a least another year.
And based on my current knowledge about the KDE4 timeframe I think that KDE3 
will be the commonly deployed KDE platform for about the same time.

So, if I want to offer some technology for third party developers to use KDE 
features, my options are kind of limited to:

- using the current Qt3 D-Bus bindings (they don't even have implementations 
for all methods they have declared)

- using new Qt3 bindings

- re-implementing all relevant KDE classes to not require KApplication (e.g. 
KRun)

- transparently creating KApplication instance (I did this before but it is an 
artificial restriction)

- creating external tool programs that can do the KDE communication

No 1 is IMHO not viable, No 2 is the one I am currently testing, No 3 is too 
much work, No 4 has proven to be awkward.
Granted, No 5 would work as well, but given my experience with kabcclient it 
is quite some work.

I also hope to be able to implement some of the ideas/specs the Portland 
project group might come up with :)

Cheers,
Kevin
