Lets clarify again.
        Open Source not always == FREE

So using of term Open source is not accurate here.

Now let me give few my points :-)

1) I hope you know that DBMS market by price is still number one of software
market. Even although 10-15 years exists free db solutions. Why?
Why people still pay 7-8 billions of dollars per year for commercial DBs ?
Try to think about this.

2) when you say about interesting project which need unlimited,
    I start wonder what this can be a project?

    a) APPLICATION for small business office?
        it needs unlimited? NO. It needs 5 connections in 80% cases

    b) APPLICATION for Schools?
        May need 20-50 connections in class.
        but question is -- if they should be simultaneous ?

    Point is that Valentina offer royalty free Embedded Server with 5
    simultaneous connections. It is easy write code which connect/disconnect
    after send of query. We have developers that use this technique for
    schools. So they DO NOT need additional connections at all.
    This connect/disconnect technique with success can handle
    easy 20-50 clients around.
    c) APPLICATION for Business Office with 50-100 users?
    This is not small business. Such business is ready pay
    for $20-70 at least per user/connection. If you sale for less
    you loose your profit. So if you sale $20-70 its not big problems
    pass $1-20 to db vendor ?
    d) APPLICATION for Enterprise office with 1000 users?
        See (c)

    e) inet site? 
        this is not APPLICATION.

So Luis, what project you can want?
Again I want underline, Lynn have develop perfect license for Valentina, to
be able satisfy as $20-SHAREWARE developers, so small business and
educational market developers. And if your needs not fit our license you
always can call to Lynn to make some special agreement.
