상업업 프로그램 배포시 putty 를 같이 배포하는게 문제가 되나요?

상업용 제품에 putty 를 같이 넣어서 배포할려고합니다.
설치시에도 putty 라이센스도 같이 첨부할거구요.
전혀 putty 를 변경하거나, 그렇지는 않고, 바이너리만 첨부해서 상업용제품과 갈이 배포할려고합니다.(상업용이라 소스는 비공개)
telnet /ssh 기능이 필요해서 단지 프로그램내에서 telnet /ssh 기능시에 putty 가 호출되게 하려고 합니다.
문제가 될까요?
아래 라이센스상으로 봤을때는 전혀 문제가되지 않을것 같아 보입니다만. 혹시나 해서..
아시는분들 답변 부탁드려요. 날씨가 무지 덥네요. 헉헉.

(혹시 gpl이 아닌 LGPL 프로덕트도 소스 공개없이 이런식의 첨부 배포가 가능할까요--; 이건 안될것 같습니다만..)

참고로, 아래는 putty 라이센스입니다.
