Здравствуйте, Gollum и Олег Гашев, вы писали:

--- мне тоже понравился этот пример, но возможно с неожиданной для вас стороны:

1. Размер дистрибутива "компонент": 9.5Мб (подумайте об исходящем трафике и потенциальных пользователях --- им качать, а вам платить за трафик: допустим 1000 скачиваний в месяц (очень слабый поток по меркам shareware) --- почти 10Гб исходящего трафика и далеко не факт, что хотя бы 1% из скачавших купят эти компоненты).

2. Комментарий одного из пользователей к дистрибутиву:

It's a shame that the installer for the demo was unreliable. I had to copy it onto a CD to install it. Good controls spoilt by strange installer.

3. Требования к железу:

Disk Space Required: 20MB
Memory Required: 32MB (я так понимаю это столько компоненты будут занимать в памяти)

3. Лицензионное соглашение, просто песня (выделение некоторых пассажей мое):

--- я понимаю, вы, конечно, сделаете лучше и с открытыми исходниками. Но я боюсь, что объем реальных продаж у вас будет ничтожен. ИМХО, конечно.

Удачи...
