Maxium URL acceptable length

[Pedro David Marco]

Hi,
What is, in your opinion, the maximum URL acceptable length?
I am not speaking about RFCs or defacto browsers limits, etc.... i am just 
asking you for personal opinions, please...
Many browsers do not bookmark over 300 octets (aprox), and do not show in 
address-bar over 2500 octets (aprox). 
Opinions, please??? does it make sense an URL of 100.000 octets, for example???
Thanks...
