Collect additional information by using custom fields

Hi,

At a new site I'm working at, anonymous users must be able to make a donation and leave some additional textual information. First I tried e-commerce.module but it seems that the options I need are not implemented. Now I'm looking at lm_paypal.module and therefore I would like to ask the same question (see http://drupal.org/node/127346):

At a new site I'm working on, I'd like to have a donation button (or otherwise the possibility to order a non shippable product/service with a price the customer just wants to pay). But, when an anonymous user decides to donate (or purchase the service), it's necessary to collect some additional textual information. Think about company name, url, contactman, phone number, promotional text - to publish (title, first paragraph/excerpt, second paragraph), et cetera.

It seems that a lot of people are looking for something like this (in e-commerce module), but I haven't found a solution yet:

- http://drupal.org/node/81530
- http://drupal.org/node/81532
- http://drupal.org/node/106798

Can it be done by using lm_paypal?
If not, are there any plans to implement this in future versions?
And is there an easy way to integrate lm_paypal with webform.module to make it possible?

Thanks for the reply!

Cheers,
Marc
